Imanol Fernandez d5b80b872a Bug 1633725 - Improve WebXR Garbage Collection. Respect XRRigidTransform.inverse and XRView.transform [SameObject] requirements. r=kip,daoshengmu,jgilbert
- Lazily create XRRigidTransform DOMPoints
- Reuse XRRigidTransform inverse (SameObject in the spec)
- Reuse XRView transform (SameObject in the spec)
- Reuse XRWebGLLayer viewport instances
- Pool XRViewerPose instances
- Pool XRFrame instances
